Abstract

Biodiversity measurement served as baseline data for the development of effective conservation plans. The accuracy of the measurement was highly dependent on the size of the sample plot. Even though Indonesia had various ecosystems, the standard sample plot size for measuring plant species diversity was only available for lowland, lower montane, and mangrove forests. Therefore, this study aimed to determine the optimal dimension of plots for measuring plant species diversity in coastal forest ecosystems. The data was collected in Ujung Kulon National Park using various dimensions of sample plots ranging from 2 m × 2 m to 150 m × 50 m. Furthermore, the rarefaction method and species-area curve were used to examine the data. The curves showed that the optimal sample plot dimensions for seedling, sampling, and pole levels were 110 m × 50 m and 150 m × 50 m for tree stages.

Abstract

Information of vegetation structure and composition of terrestrial flora biodiversity can be measured by vegetation analysis method. The method requires sampling plots as a measurement plot capable to describe species in a forest stand. The distribution of a species of diversity, especially plants, is relatively dependent on the type of plant with the condition of the area it occupies. Therefore, an efficient and representative method is needed for the ecosystem in measuring. The objective of the study was to determine the optimal shape and size of sample plots for measuring plant species diversity at stake in TNGHS as well as to assess the most responsive diversity index. The results showed that the shape and size of the optimal sample plot for measuring plant species diversity at stake in TNGHS was a rectangular plot measuring 3.200 m2. The result of the index processing of diversity, it was found that the Margalef Index gave a more responsive diversity value to the change of species number compared with Menhinick, Simpson and ShannonWiener indices. Key words: composition, diversity index, margalef, structure, terrestrial flora.

Abstract

The assessment of the oil palm plantations impact on biodiversity mostly compares oil palm plantations to natural forests. But in reality, most land cover type before oil palm plantations establishments are no longer primary forest. Observations were made on 2 large holding plantations (PSB) in West Kalimantan Province. Tracking data on the origin of land cover types was carried out by interview method and analysis of interpretation of land-satellite imagery. The results showed that the baseline PSB studied were shrubs/fields and secondary forests. The number of species (mammals and birds) in the oil palm area is higher than the baseline area. PSBs establishment that are originally in the form of shrubs/fields has affect in increasing diversity of mammals (3 species) and birds (11 species). The same results are also shown in areas that are originally in the form of secondary fields and forests, has also increased the number of species of mammals (5 species) and birds (18 species). Thus, it can be concluded that the land cover changes in 2 oil palm plantations studied has a positive impact on the mammals and birds’ species diversity

Abstract

A person may contribute to the conservation of species through donations. The willingness to donate (WTD) to conserve endangered species can depend on many factors. This research aims to determine the willingness of visitors to Indonesia's zoos and safari parks to make a donation for species conservation and identify the determinants of their WTD through preferences toward certain species. This research focused on 12 priority endangered mammals. The study began with a preliminary survey of 110 respondents in January 2020, followed by data collection in February 2020 involving 1011 adult visitors to zoos and safari parks in Java and Bali. Specifically, descriptive statistics in the form of percentages ere used to analyze the influence of preferences toward species conservation and amount of donation while considering individual characteristics such as gender, age, place of residence, occupation, and level of education. Our results confirmed that mammals, mega-herbivores and large carnivores are very popular among young adult visitors. Overall, the results demonstrated that visitors placed rhino, elephant and tiger as the three priority species to be conserved in terms of donation given. It is clear that these three charismatic species have a very high conservation value in the eyes of the people. Furthermore, the characteristics of species and the knowledge and psychological preferences of the visitors can contribute to the determination of the preference for the number of donations to certain wildlife species. Key words: charismatic species, conservation institutions, demographic characteristics, Indonesia, primate

Abstract

Illegal wild animal trade is a conservation threat, predominantly in Indonesia. Most of the animals traded is the pangolin which almost all parts of the body are used, especially the scales. This research used a bibliometric review that uses Scopus, The Web of Science platform, and Google Scholar to analyze publications for one decade to map trends and gaps in pangolin research. The result of this research showed that the total of publications significantly increased over several decades, but the topic for pangolin research is not learned in the same proportion (only 37% of them discussed the population appraisal of pangolin in the wild, the remainder mostly discussed status and conservation of pangolin in 41%, and the effect of illegal pouching and trading in 22%). There is an inconsistency between the researchers in developed countries and developing countries where more research is conducted in developed countries than in developing countries. The data from the analysis research collected systematically in developing countries were not published proficiently, therefore it caused several publications to fall into the grey literature category. There are some research gaps, which are research topics are not diverse and have too many things in common, other than that the population data are not aligned with the biodiversity distribution and conservation priorities, especially concerning endangered species such as pangolins. The success of conservation relied on the policymakers and practitioners, and the implications of this research gave suggestions for the management to overcome the pangolin trade polemic that has become increasingly widespread recently.

Abstract

Within the last few decades, oil palm (Elaeis guine) has become one of the most rapid crop plantations being widely cultivated in Indonesia. Land clearing for stallholder plantation is made by people, either individually or in group. Forest clearing for planting activities may cause changes to the composition of the ecosystem. Birds have a signifcant role in the ecosystem, such as pollinators, seed spreader and pest control. It was claimed that bird richness decreases at least 60% due to changes in land cover into plantations. This claim needs to be further verifed. The objective of this study is to identify bird diversity and determine thesimilarity of the bird community in some smallholder oil palm plantations in Kuantan Singingi, Pelalawan and Siak District in Riau Province. Data collection had been conducted using transect method with length of 1 km and width of 50 m. Observations were done at 8 smallholder oil palm plantations in the morning from 6:00 to 8:30 pm and in the afternoon from 15:30 to 18:00 pm with 3 times repetition. Data in the study were analyzed by Margalef Index (Dmg), evenness (E) and community similarity (IS). This research showed that there are 22 species of birds from 15 families. The highest value of diversity and richness was in the plantation 1 while the highest evenness was in the plantation 5. The lowest diversity was in SH5 (H '= 1.79), the lowest richness was plantation 6 (Dmg = 2.50) and the lowest evenness value was in the plantation 4 (E = 0.90). The highest value of community similarity recorded between plantation 1-plantation 4 (IS = 0.92) while the lowest was seen between plantation 5-plantation 7 (IS =0.44). Similar habitat conditions a?ect the value of the bird community similarity.

Abstract

The extent to which oil palm has contributed to deforestation of primary forests is still an intensive debate in public space. Even though the term deforestation and the results of the study and study are still "debatable" and have not been scientifically valid, they have had a very debilitating effect and detrimental to Indonesia's position in global trade because it is considered responsible for the destruction of primary natural forests in the Southeast Asia region. Therefore, since 2015, research has been carried out on the origin of status, history of land use, land-cover and biodiversity in several oil palm plantations in 6 provinces (Riau, North Sumatra, South Sumatra, Central Kalimantan, West Kalimantan and West Sulawesi). The results of the search for the origins of the status of oil palm plantations (according to the RTRWP) show that 98.56% of the candidates for oil palm plantation areas are "not forested", namely: APL (54.93%), Plantation and Agriculture (42.19%). Furthermore, the results of interpretation of Landsat imagery on the condition of vegetation cover at 1 year before being made into oil palm plantations indicate that the type of land cover is no longer in the form of primary forest, but already in the form of shrubs and bare-land or rubber-plantation (68,91%). Likewise with the results of the search history of land use (see slide) where 71.29% of the land under study is the land of ex-community gardens, fields, transmigration land, or ex-HGU of other companies. While the rest (28.71%) is ex-HPH land. Referring to the juridical definition of "deforestation", this data shows that oil palm plantation land which is the location of the study "is not the result of deforestation". Referring to both the juridical definition and the FAO/World Bank definition of "deforestation", this data shows that oil palm plantation land which is the location of the study "is not a direct cause of primary deforestation".

Abstract

Currently the expansion of oil palm is increasing, which at the same time creates a lot of negative responses related to environmental impacts, biodiversity loss, including birds and butterflies species diversity. Nowadays our understanding of the impacts of oil palm plantations is still based on the claim that oil palm plantations are established on primary forest land. The study aimed to estimate the impact of land cover changes, loss of biodiversity, and possible cohabitation between birds and butterflies based on baseline land type before oil palm plantation. The research was conducted at PT Tempirai Palm Resources, to be precise, in the baseline area (shrubs) and plantation areas planted with oil palm using direct and indirect observation methods. Based on research, it was known that land conversion to oil palm plantations caused changes in the number of species, and the diversity of birds and butterflies. The number of bird species in the baseline area was higher (S = 22 species, H ‘= 2.51) than in the plantation area. The number of butterfly species in the baseline area was less (0 species) than in the oil palm plantation area (5 species, H ‘= 1.56, Dmg = 2.23). In general, the increase in bird species’ biodiversity was higher (59.09%) compared to the loss. In contrast, the butterfly species was not lost. A cohabitation also occurred between birds and butterflies at the site. The study concluded that oil palm plantation not only have a negative impact but also a positive impact for biodiversity especially for bird and butterfly.­­­­

Abstract

Keberadaan perkebunan kelapa sawit rakyat berdampak pada dampak lingkungan, sosial dan ekonomi bagi masyarakat sekitar. Penelitian ini bertujuan untuk mengkaji persepsi masyarakat terkait budidaya kelapa sawit, dampak lingkungan, sosial, dan ekonomi dari keberadaan kelapa sawit rakyat. Pengumpulan data dilakukan dengan wawancara terstruktur dengan kuesioner dan observasi lapangan. Hasil penelitian menunjukkan bahwa sebagian besar masyarakat memiliki persepsi positif terhadap keberadaan kebun sawit rakyat. 40% masyarakat setuju terkait budidaya dan keberadaan dari kebun sawit rakyat. Masyarakat di Desa Balian tidak melihat pengaruh yang signifikan terhadap dampak keberadaan kebun sawit rakyat terhadap lingkungan, sehingga mayoritas bersifat netral (39%). Masyarakat menyatakan bahwa kebun sawit tidak merusak lahan, tidak mencemari sungai, dan berpotensi menjadi habitat satwa liar. Namun, persepsi terhadap kualitas udara dan air cenderung netral. Mayoritas masyarakat Desa Balian juga merespon netral pada dampak sosial dari keberadaan kebun sawit rakyat (51%). Masyarakat menyetujui bahwa kebun sawit meningkatkan interaksi sosial dan partisipasi pemuda, meskipun pelibatan perempuan masih perlu ditingkatkan. Walaupun lebih banyak merespon netral tetapi yang menyatakan setuju juga lebih banyak dari respon tidak tahu dan tidak setuju pada aspek lingkungan dan sosial. Sedangkan untuk dampak ekonomi, persepsi masyarakat sebagian besar positif (40%). Masyarakat setuju terhadap kontribusi kebun sawit dalam memenuhi kebutuhan keluarga, meningkatkan pendapatan, serta membuka lapangan pekerjaan. Namun, terdapat tingkat ketidaktahuan yang cukup tinggi terkait aspek permodalan. Penelitian ini memberikan dasar bagi pengambilan kebijakan yang mempertimbangkan keseimbangan antara manfaat ekonomi dan tanggung jawab ekologis dari keberadaan kebun sawit rakyat.Kata kunci: persepsi masyarakat, kebun sawit rakyat, lingkungan, ekonomi, sosial

Abstract

Until now, conflicts between elephants and the community are still occurring, one of which is in the Bukit Barisan Selatan National Park. This conflict has a negative impact on both elephants and society, so it is necessary to examine the habitat factors that determine the movement of Sumatran elephants. Therefore, the aim of this study is to determine the daily movement of the elephants and to analyze the habitat factors that influence elephant movement. Data was collected in the form of elephant movements in one period which were obtained from the Bukit Barisan Selatan National Park. 1-year results obtained from the GPS stated that there are two groups of elephants, the citra elephant group and the bunga elephant group. The results showed that groups of elephants in Bukit Barisan Selatan National Park have lengths that ranged from 63 – 137 kilometers, with linear, zigzag and circular trajectories, and the frequency of points used is 2-6 repetitions with the time needed per-kilometers ranging from 110 – 518 minutes. Factors that influence elephant movement are track length, frequency of point used, time spent per-kilometers, altitude, slope, distance to settlements, distance to water sources, availability of feed, and availability of scrubbing trees
